Abstract: User profiles of remote desktops are managed in a crash-consistent manner. When a user logs into a remote desktop, metadata of the user profile is loaded from persistent storage while registry settings and files of the user profile are loaded asynchronously with respect to the login. During the remote desktop session, snapshots of the remote desktop image in persistent storage are generated periodically, and a change log that indicates changes to the user profile is created therefrom. The user profile stored in persistent storage is updated lazily using the change log at opportunistic times after snapshot generation. When the user logs out of the remote desktop, the user profile stored in the persistent storage is updated with any additional changes to the user profile by extracting the changes from the copy-on-write cache associated with the most recent snapshot.

Abstract: Elements of drop-stitch material are formed into different structures. In a platform, two legs support a horizontal platform. All are of drop-stitch material, which can be inflated to sufficient pressure for it to be rigid. Valves between the legs and platform allow air to flow between the legs and the platform. Another design is a luggage or cargo carrier for vehicles with a base, top and front walls formed of interconnected drop-stitch material. When the drop-stitch material is inflated, the material forms a cavity which receives luggage or other items. Sidewalls create an enclosed space. elements of the drop-stitch material can form other structures such as a truck shell with openings through the material to acts as windows or a door.

Abstract: A rocket fueling system includes an insulated jacket configured to removably couple to at least a portion of a rocket and form an enclosed space between the insulated jacket and the at least the portion of the rocket. The rocket fueling system also includes a cryogen inlet in the insulated jacket. The cryogen inlet is configured to receive a cryogen into an interior chamber of the insulated jacket. The rocket fueling system further includes a cryogen outlet in the insulated jacket. The cryogen outlet is configured to provide the cryogen from the interior chamber in the insulated jacket to the at least the portion of the rocket in the enclosed space. The rocket fueling system still further includes a gas outlet in the insulated jacket configured to exhaust the cryogen from the enclosed space, and a flammable gas sensor configured to detect a flammable gas at the gas outlet.

Abstract: A toroidal microinductor comprises a nanocomposite magnetic core employing superparamagnetic nanoparticles covalently cross-linked in an epoxy network. The core material eliminates energy loss mechanisms in existing inductor core materials, providing a path towards realizing low form factor devices. As an example, both a 2 ?H output and a 500 nH input microinductors comprising superparamagnetic iron nanoparticles were modeled for a high-performance buck converter. Both modeled inductors had 50 wire turns, less than 1 cm3 form factors, less than 1 ?AC resistance and quality factors, Q's, of 27 at 1 MHz. In addition, the output microinductor had an average output power of 7 W and power density of 3.9 kW/in3.

Abstract: The present invention is directed to the syntheses of superparamagnetic nanoparticles and the incorporation of the nanoparticles as the magnetic component to form a strongly magnetic nanocomposite. The superparamagnetic nanoparticles possess no hysteresis and are too small to support eddy currents. The invention uses a ligand exchange procedure to produce aminated nanoparticles that are then cross-linked using epoxy chemistry. The result is a magnetic nanoparticle component that is covalently linked and well separated. By using this ‘matrix-free’ approach, it is possible to substantially increase the magnetic nanoparticle fraction, while still maintaining good separation, leading to a superparamagnetic nanocomposite with strong magnetic properties and low magnetic losses.

Abstract: A method for creating nanoparticles directly from bulk metal by applying ultrasound to the surface in the presence of a two-part surfactant system. Implosive collapse of cavitation bubbles near the bulk metal surface generates powerful microjets, leading to material ejection. This liberated material is captured and stabilized by a surfactant bilayer in the form of nanoparticles. Nanoparticles can be produced regardless of the bulk metal form factor. The method is generally applicable of metals and alloys. The method can be applied to an environmentally important problem, the reclamation of gold from an electronic waste stream.

Abstract: The invention provides a green chemistry, aqueous method to synthesize gold nanoparticles directly from bulk gold sources. The method involves the ultrasonication of bulk gold in water in the presence of an alkythiol species and a quaternary ammonium surfactant. An organic bilayer forms on the surface of the gold which renders it susceptible to material ejection from the violent collapse of cavitation bubbles. This ejected material is stabilized in solution by the formation of an organic bilayer and can be easily separated. It can then be subjected to an aqueous digestive ripening step to give a gold nanoparticle ensemble with a well-defined plasmon resonance. This method is applicable to a number of different sources of bulk gold. The method can be applied to an environmentally important problem; the recovery of gold from electronic waste streams. For example, gold nanoparticles can be extracted directly from the surface of SIM cards, with no prior manipulation of the cards necessary.
